// With 'build' we get a "live" function that can send to a target/server, use it to log// You can have one of these in each of your module "screens"/parentsconst sendMessage = build(logary, getLogger(logary, "MyModule"))
// Send a message!// You can have one of these whereever you need to track stuff!
